Supervolcanoes Discovered in Utah by BYU Geologists

Brigham Young University geologists found evidence of some of the largest volcanic eruptions in earth’s history right in their own backyard.

These supervolcanoes aren’t active today, but 30 million years ago more than 5,500 cubic kilometers of magma erupted during a one-week period near a place called Wah Wah Springs. By comparison, this eruption was about 5,000 times larger than the 1980 Mount St. Helens eruption.

“In southern Utah, deposits from this single eruption are 13,000 feet thick,” said Eric Christiansen, the lead author for the BYU study. “Imagine the devastation – it would have been catastrophic to anything living within hundreds of miles.”
